What Happens First ?

A block is connected to an identical block through a weightless pulley by an inextensible thread of length \(2L\) (see figure). The left block rests on a frictionless table at a distance \(L\) from its edge, while the right block is kept at the same level so that the thread is unstreched and does not sag, and then released.
What will happen first: will the left block reach the edge of the table (and touch the pulley), or will the right block hit the table?

The left block will first reach the end of the table.The right block will hit the table first.Both will happen simultaneously.Nothing can be concluded.
